The colour reaction of TMB-4 and palladium(II) chloride has been investigated. The optimum reaction conditions, spectral characteristics, stability constant and composition of the yellow water-soluble complex have been established. A new spectrophotometric method is proposed for microdetermination of TMB-4.
